seeking advice for a modular build system

[Hans-Christoph Steiner]

Hey all,

I am starting the process of creating an autotools build system for  
Pd-extended, a large distro of a program called Pure Data and many  
libraries.  Pure Data is a realtime visual programming language for  
sound, video, etc.  Over the years, there have been quite a few  
libraries written for it.  Currently, I have a big hacked Makefile  
that builds all of the libraries.  I would like to replace this with  
an autotools system.

One thing that I would love to have is flags to ./configure to enable/ 
disable the inclusion of different libraries.  The libraries are  
currently in subdirs named with the library name.  I am wondering how  
to best to that with autotools.

Another thing, each of the libraries are made up of  
one .so/.dylib/.dll for each objectclass.  I am wondering what the  
best method for having separate CFLAGS and LDFLAGS for each library.   
I want to do that in case different libraries depend on different  
versions of the same lib.  Perhaps I need some kind of recursive ./ 
configure system.

Thanks in advance!
